Inside the Kamui dimension, after completely gaining control over the Giant Tenseigan, Ryun sent it to the highest point of the space to serve as the sun of life illuminating the small world.
The light slowly released from the Giant Tenseigan contained a special kind of life energy. Being bathed in this light for a long time made Ryun feel very warm and comfortable.
"It truly is a 'treasure of the Otsutsuki'. It is just a pity that crafting such a treasure consumes too many Byakugan."
The Giant Tenseigan was an aggregate product of Otsutsuki Byakugan. The eyes and chakra of Hamura's descendants on the moon were almost all inside here.
The Hamura clan had purely 'burned themselves to illuminate Ryun'. In his view, they were a group of great people.
"Having only water and earth is far from enough. The world should not be so monotonous. Also, it cannot rely solely on the Giant Tenseigan as the energy source for operating the world. Other energy sources are needed."
The image of the Loulan Dragon Vein surfaced in Ryun's mind. He wanted to build the Kamui dimension into an excellent paradise, so abundant natural energy was absolutely indispensable.
He decided to act immediately. Ryun temporarily exited the Kamui dimension and, using a space technique, quietly appeared within the Dragon Vein.
He moved half a pool of the Dragon Vein spiritual liquid into the Kamui dimension. The natural energy within the entire small world instantly became much denser.
Sensing the natural energy dispersing in the air, Ryun could not help but sigh slightly. He felt it was still not enough. It was just a pity that he could not extract more spiritual liquid from the Dragon Vein.
"It seems I need to make a trip to the three great sage regions."
Ryun murmured to himself. He was setting his sights on the three great sage regions. Those three summoning realms possessed extremely dense natural energy. He could completely use sage methods to 'transport' that natural energy.
"Wait, how could I have forgotten about it."
A flash of inspiration crossed Ryun's mind. The next moment, he exited the Kamui dimension and suddenly appeared at the foot of the Divine Tree.
A short while later, Nagato, having received the summons, also arrived at the foot of the Divine Tree.
"With your current ability, can you extract the energy of the Ten Tails Divine Tree?" Ryun looked at the other and directly asked the key question.
Hearing this, Nagato visibly froze for a moment. He had not expected Ryun to call him here for this matter.
"My body contains a different dimension, but the energy inside is too thin. If possible, I would like to channel the chakra from within the Divine Tree into the different dimension. This might make the energy inside denser."
Ryun explained the reason in one go, to avoid Nagato not knowing how to proceed.
"I will try to see if it can be done. But before that, you need to open the passage to the different dimension, right?"
A wooden tree root directly pierced the back of Nagato's neck. He began attempting simple communication with the Divine Tree.
Ryun's ocular technique activated. A spatial vortex over one person's height suddenly appeared in front of Nagato. This was the spatial passage leading to the Kamui small world.
"Try to be quick. I cannot maintain this spatial passage for too long." Ryun stated truthfully.
At this moment, it was equivalent to him continuously using the Kamui ocular technique. The consumption of ocular power was quite significant. Even though he possessed the Eternal Mangekyo Sharingan, he could not keep it open for extended periods.
"Is it only necessary to transfer the Ten Tails' energy into the different dimension?" Nagato could not help but ask one more question.
"Yes, just pour energy inside." Ryun said quickly.
"Okay."
Nagato nodded. The Divine Tree's surface instantly sprouted a large, tubular root. The root extended directly into Ryun's different dimension. Then, under Nagato's careful control, a large amount of Ten Tails chakra gushed out all at once. The energy within the Kamui dimension instantly began to become dense.
As a closed, different dimensional small world, the accumulation of energy would only gather more and more. When the vast Ten Tails power spread throughout the entire small world, the mountains, rivers, and lakes created by Ryun also began to unconsciously devour this energy. The entire world was visibly becoming more vibrant at a rapid pace.
The Ten Tails power contained seven attributes: water, earth, fire, wind, lightning, yin, and yang. A significant part of its power originally came from natural energy, so its chakra attributes were as comprehensive as natural energy.
The growth of the world could not be separated from this energy. With the assistance of the Ten Tails Divine Tree, a slight breeze gradually arose within the Kamui dimension. With the caress of the breeze, the entire small world clearly became more full of life.
It was just a pity that the good times did not last long. As a trail of bloody tears streamed from Ryun's eyes, the long maintained spatial passage abruptly closed. The Ten Tails' root, withdrawn, was severed by the spatial force.
"Whew. Let's leave it at this for now."
Ryun let out a long breath and said helplessly, rubbing his sore eyes.
In this round of infusion from the Divine Tree, the total output of energy was roughly equivalent to two Ten Tails Tailed Beast Balls.
Mainly, the spatial passage Ryun opened was too narrow, and using only a single root to channel chakra was clearly inefficient.
"I will rest first. We will continue again tomorrow."
During the break, Ryun collected some grass seeds from nature and also returned home to fetch some flower seeds.
He wanted to add other colors to his small world.
At this time, the energy within the Kamui dimension was still relatively sufficient. Part of the Ten Tails power actively integrated into the water and earth, while another part of the chakra drifted between heaven and earth like air.
Ryun buried the grass seeds and flower seeds into the soil. In just one hour, stimulated by the Ten Tails power, the grass and flowers broke through the soil one after another, their growth speed unbelievably fast.
"No. Ordinary grass seeds are not suitable for planting in this kind of place. The reproduction speed is too fast, and the invasiveness is too strong."
Looking at the wild grass that had grown half a person's height in a single day, Ryun felt a slight headache. With a wave of his hand, he destroyed a small patch of wild grass.
He wanted a patch of green grass, not large clumps of grass tall enough to play hide and seek in.
"Forget it. I will deal with this later. Let me first create an environment suitable for secluded training."
Ryun planned to have Nagato continue infusing Ten Tails chakra into the Kamui dimension. This, combined with the Ten Tails power within his own body, would allow him to cultivate both internally and externally, thereby greatly accelerating the speed of awakening his Rinnegan.
In fact, after two years of stimulation by this power, Ryun's skin tone had gradually changed from normal yellow to a moon white color. This change indicated that he was slowly transforming towards the physique of the Otsutsuki clan.
Ryun was aware of the change in his skin tone. Moreover, under the long term influence of the Ten Tails power, his Sage Body had also become increasingly powerful.
Although Ryun's Sage Body was more powerful than Hashirama's Sage Body, the robustness of their physiques was mostly manifested in recovery power. There was not much bonus to lifespan increase.
Hashirama possessed a perfected Sage Body but still died young. Because Ryun cultivated immortality year round, his body was in harmony with nature. Although his Sage Body seemed almost perfect, wanting to achieve longevity and enduring vision was still somewhat difficult.
The values for recovery, defense, endurance, and so on of his current Sage Body were almost all maxed out. Only the longevity aspect was clearly lacking.
Although the Ten Tails power had not immediately enabled him to awaken the Rinnegan, it had filled the last defect of the perfected Sage Body, causing it to gradually become a flawless, longevity Sage Body.
The Otsutsuki clan was generally long lived. Ryun had already obtained this transcendent gene from the Ten Tails power.
